* test(#3685): failing-first regression coverage for phase-complete write flags `phase complete` reports `roadmap_updated`/`state_updated` from `fs.existsSync(path)`, so both read `true` whenever the file merely exists — including when the transaction wrote nothing. Add the regression tests that prove it, plus the negative-space and true-direction pins, before the fix. New in tests/phase.test.cjs: - roadmap_updated is false when the transaction rewrites nothing (FAILS today) - state_updated is false when the transaction rewrites nothing, and stays false on a third consecutive run (FAILS today) - both flags are true when the transaction genuinely rewrites (pins the true direction so the fix cannot be tightened into always-false) - each flag stays false when its file is absent The STATE.md cases pin the clock via GSD_TEST_MODE + GSD_NOW_MS (src/clock.cts:43-70) because syncStateFrontmatter stamps a millisecond-resolution `last_updated:` on every write, which would otherwise make the no-op unobservable. Also strengthens four pre-existing `=== true` assertions on these fields that passed vacuously: each now pairs the flag assertion with a content-changed assertion against a pre-call snapshot, so the `true` is earned. Refs #3685 * fix(#3685): report phase-complete write flags from the transaction, not the filesystem `phase complete` computed `roadmap_updated` and `state_updated` as `fs.existsSync(path)`, so both read `true` for any project that had the file at all — including a run that rewrote nothing. The flags are the only signal a caller has that the rollup landed, so a no-op was indistinguishable from a successful write and a stale ROADMAP went unnoticed until something downstream read wrong numbers. Both flags now reflect whether that file's content actually changed in the transaction, computed at the existing `writes.push({filePath, before, after})` sites — the same contract `requirements_updated` has honored since #2316-3, and the same correction #2640/#2974 already applied to `phase remove`. Nothing about what gets written changes; only what gets reported. Fixes #3685 * chore(changeset): backfill PR number for #3685 fragment --------- Co-authored-by: sim <sim@local>
GSD Core
Git. Ship. Done.

A light-weight meta-prompting, context engineering, and spec-driven development system for Claude Code, OpenCode, Antigravity CLI, Kimi CLI, Kilo, Codex, Copilot, Cursor, Windsurf, and more.
What is GSD Core
GSD Core is a context-engineering and spec-driven development framework that drives AI coding agents (Claude Code, Codex, Antigravity CLI, Kimi CLI, Copilot, Cursor, and more) through a disciplined phase loop. It solves context rot — the quality degradation that accumulates as an AI fills its context window — by running all heavy research, planning, and execution work in fresh-context subagents while keeping your main session lean.
How it works
Each milestone repeats the same five-step loop, one phase at a time:
- Discuss — capture implementation decisions before anything is planned
- Plan — research, decompose, and verify the plan fits a fresh context window
- Execute — run plans in parallel waves; each executor starts with a clean 200k-token context
- Verify — walk through what was built; diagnose and fix before declaring done
- Ship — create the PR, archive the phase, repeat for the next one
Quickstart
npx @opengsd/gsd-core@latest
The installer prompts for your runtime (Claude Code, OpenCode, Antigravity CLI, Kimi CLI, Kilo, Codex, Copilot, Cursor, Windsurf, and more) and whether to install globally or locally. The installer is required for cross-runtime compatibility — do not copy files from agents/ or commands/ directly.
On another runtime or without Node.js? See Install on your runtime.
Once installed, start a new project or onboard an existing repo:
/gsd-new-project # greenfield project
/gsd-onboard # existing codebase

Why it works
Most AI-coding setups fail at scale because context bloat silently degrades output quality, there is no shared memory between sessions, and nothing verifies that code actually works. GSD Core solves all three: heavy work runs in fresh subagents, structured artifacts like STATE.md and CONTEXT.md survive session boundaries, and the verify step walks through what was built and generates fix plans before a phase is declared done. See docs/explanation/context-engineering.md for the full reasoning.
